The Intel Core 3 305 is a 6-core, 6-thread low-power mobile and embedded processor from Intel’s Wildcat Lake (Core Series 3) family, built on the Intel 18A process and targeting value laptops, Chromebooks, and edge AI devices with hybrid CPU cores and Xe3 integrated graphics.
Intel’s Core 3 305 brings the Wildcat Lake architecture to value mobile and embedded devices. It has two Cougar Cove performance cores and four Darkmont low-power efficiency cores for a total of six threads, plus 6 MB of shared L3 cache and a single-channel DDR5/LPDDR5X memory controller. The integrated Xe3 GPU with 16 EUs and AV1 decode is a notable upgrade over older UHD Graphics solutions, while the 15 W base / 35 W turbo power envelope enables thin, fanless designs.
It’s best for everyday productivity, light creation workloads, and edge AI rather than heavy gaming or content creation.
Specifications
Performance
Six threads and high P-core turbo frequencies make the 305 responsive for office work, web, and light creative tasks, though it’s not meant for heavy multi-threaded workloads.
VT-x and VT-d are supported, but limited cores, memory channels, and PCIe lanes constrain its use as a virtualization host beyond light VMs.
The 1-core Xe3 iGPU with 16 EUs is enough for very light or older titles at low settings, but not for serious 1080p gaming. AV1 decode and modern display outputs are more relevant than raw frame rates.
The 15 W base power and Intel 18A process deliver strong performance per watt, ideal for thin, fanless, or battery-first designs.
- •1-core Xe3 iGPU with 16 EUs targets very light gaming and media playback, not 3D AAA titles
- •AV1 decode and modern display outputs (DP 2.1, HDMI 2.0b) are more relevant than high FPS
- •Best suited for cloud gaming or older/low-demand games at 1080p Low
- •No dedicated NPU on Core 3 305; NPU is present only on higher Wildcat Lake SKUs like Core 3 304
- •Intel Deep Learning Boost on CPU and GPU provides int8 acceleration for lighter AI workloads
- •OpenVINO, DirectML, WindowsML, WebNN frameworks are supported
- •Suitable for on-device inference (vision, audio, small models), not large LLM training

Architecture Overview
Wildcat Lake is Intel’s value-oriented mobile SoC family built on the same Intel 18A process and core IP as Panther Lake, but with fewer GPU and NPU resources and a right-sized feature set for budget and edge devices.
CPU Design
The Core 3 305 uses two Cougar Cove performance cores (1.5–4.3 GHz) and four Darkmont low-power efficient cores (1.4–3.3 GHz) in a 2P+4LPE layout with no traditional E-cores. This hybrid design balances bursty foreground tasks and background work within a 15 W base / 35 W turbo envelope, with Thread Director guiding the OS scheduler.
Memory Subsystem
A single-channel memory controller supports up to 64 GB of DDR5-6400 or LPDDR5X-7467, prioritizing cost and simplicity over bandwidth. This is sufficient for everyday workloads but limits performance in bandwidth-heavy applications.
PCIe & I/O
Six PCIe 4.0 lanes from the CPU (configurable as x4 + 3x2 or 6x1) provide basic expandability for NVMe SSDs and peripherals, but not for multiple high-bandwidth devices.
Overclocking
The multiplier is locked and there is no unlocked overclocking support; turbo frequencies are managed by Intel Turbo Boost 2.0 within the 15–35 W power envelope.
- Move from pure E-core design to hybrid 2P+4LPE with much higher single-thread performance
- New Xe3 iGPU with AV1 decode instead of older UHD Graphics
- Intel 18A process with significantly better performance per watt than Intel 7 (Alder Lake-N)
- Modern I/O including Thunderbolt 4, Wi-Fi 7, and PCIe 4.0
Key Highlights
- Modern Intel 18A process with strong performance per watt
- Hybrid 2P+4LPE core design improves responsiveness vs older E-core-only designs
- Xe3 iGPU with AV1 decode and modern display outputs (DP 2.1, HDMI 2.0b)
- 15 W base power enables thin, fanless, or always-on edge designs
- Full VT-x and VT-d virtualization support
- Embedded-friendly BGA package with industrial temperature options
- No NPU; AI features rely on CPU/GPU DL Boost only
- Single-channel memory controller limits bandwidth for heavy workloads
- Only six PCIe 4.0 lanes restrict expansion
- 1-core Xe3 iGPU with 16 EUs is weak for 3D gaming
- Locked multiplier with no overclocking support
- L3 cache only 6 MB; L2 breakdown not specified by Intel
History
Intel’s Wildcat Lake Core Series 3 family emerged in early 2026 as the value-oriented counterpart to the higher-end Core Ultra Series 3 (Panther Lake) platform. Leaks and OEM product sheets through the first quarter of 2026 detailed a 6-core, 2P+4LPE design with Xe3 graphics and 6 MB of L3 cache, initially with SKUs like Core 3 304 and Core 5 320. Intel officially launched Core Series 3 on April 16, 2026, emphasizing everyday computing, battery life, and AI-readiness for students, small businesses, and edge devices rather than enthusiasts or creators.
The Core 3 305 sits in the lower part of this stack as a 6-core, 6-thread part with one Xe3 GPU core and no NPU, focusing on cost and efficiency over AI TOPS. Early PassMark benchmarks show it roughly matching Apple’s A18 Pro in multi-threaded performance and slightly trailing in single-thread, but these results come from small sample sizes and should be treated as preliminary. Industrial SBCs such as Advantech’s MIO-5356 were among the first commercial products to list the 305, targeting embedded and edge AI use cases where its 15 W power and modern I/O are more important than peak CPU or GPU performance.

Interesting Facts
Wildcat Lake is Intel’s first non-Ultra Core Series 3 family built on the same 18A process as Panther Lake, scaled down for value devices.
The Core 3 305 uses two P-cores and four LPE-cores but no traditional E-cores, a distinct layout from Alder Lake-N’s pure E-core design.
Unlike the higher Core 3 304 SKU, the 305 does not include an NPU; AI acceleration is CPU+GPU only.
The 1-core Xe3 iGPU is the smallest configuration in the Wildcat Lake lineup, with higher SKUs offering two Xe3 cores.
PassMark sightings show multi-thread performance slightly above Apple’s A18 Pro and around the level of some 15 W Ryzen 3 U-series chips, but with limited sample size.
Intel markets Core Series 3 as “AI-ready” even at this SKU level thanks to DL Boost and GPU AI support, though not as an “AI PC” in the NPU-heavy sense.
The 6 PCIe 4.0 lanes can be flexibly configured as x4 + 3x2 or 6x1 to match different BOM priorities.
Despite being a mobile/embedded BGA part, the 305 supports up to 64 GB of DDR5/LPDDR5X, which is generous for its segment.
Advantech’s MIO-5356 SBC is one of the first documented industrial boards using the Core 3 305, targeting edge and IoT applications.
The 18A node with RibbonFET and PowerVia represents Intel’s move to gate-all-around transistors and backside power delivery, a major shift from FinFET.
